April showers bring May flowers, but they may also bring increased asthma attacks for those whose asthma is triggered by allergens. While rain can help your air quality by washing away pollutants that may be lingering in the air, a 2008 study by scientists at the University of Georgia and Emory University, found that emergency room visits for asthma attacks would rise in the days following a thunderstorm. They discovered that the wind and rain during a thunderstorm can break apart pollens into smaller pieces, making them easier to spread throughout the air and cause irritation to lung tissues. When winds pick up after a storm, they carry these tiny pollutants with them, and if sufferers are not prepared, then they may experience a sudden and surprising increase in their symptoms.

Managing triggers is one of the most important parts of a comprehensive asthma prevention plan, and research like this may help sufferers to better plan and prepare for the times when they need to exercise caution and keep inhalers or other medicines close. Keeping an eye on local pollen counts can also help sufferers by showing when pollens counts are highest, so that they can avoid going outdoors during peak times. While indoors, asthma sufferers can protect themselves from pollen and other irritating pollutants, by running an air purifier with a true HEPA filter, such as our MinusA2. By preparing for asthma triggers after a thunderstorm, sufferers can spend less time wheezing and more time splashing in puddles and enjoying the springtime showers.
